Acombinational logic circuit has four inputs (a, b, c, and d. and one output z. the output is 1 iff the input has three consecutive 0's or three consecutive 1's. for example, if a = 1, b = 0, c = 0, and d = 0, then z = 1, but if a = 0, b = 1, c = 0, and d = 0, then z = 0. design the circuit using one four-input or gate and four three-input and gates.
